If someone is making a variant, they will want to copy/paste text but also have access to tables. So I guess #2 is ideal in that case. #3 is nice, but I believe the art is not free for them to use in their own product? Otoh, if they are making a custom booklet just for their gaming group, #3 is ideal. I guess I can't decide!

Yeah, after sleeping. My brain is working better. I'll do the first 2 options. Not sure about the 3rd yet. It would need a huge disclaimer that the art is copyrighted and for home use only. I checked with William McAusland already and he was ok with it.
